EXPORTING HDV 1080 25p is giving jumpy image at DVinfo.net

Hello, thank you very much for your handy threads.

I have a question, a problem with my exportation that doesn't let me sleep.

I'm editing HDV 1080 25p footege recorded with the Canon XHA1 in FCP 6.06. MACOS X 10.5.6 LEOPARD Proc.2.8 GHZ Intel Core 2 Duo, 2GB DDR 2 SDRAM 800M.

My finished timeline is 7 minutes. Some effects, some LiveType titles (a little sawtooth like in the edges), and all looks good so far. The settings are HDV1080 25p timeline.

Now, I want to create a master with best resolution and best compatibility, I do not mind the file size.

I'm doing several tests and I'm not really satisfied.
The timeline looks perfect but once created the Quicktime file the image is jumping slightly, stumbling, the larger the file bigger the jumps. But once copied to a data file DVD is terrible, the picture is very jumpy and keeps on stopping.

I exported with and without Quicktime conversion. In different codecs: HDV1080 25p, in ProRes 422 HQ normal (before rendering in ProRes too). Frame rate 25, size 1440x1080. AAC.
The timeline looks perfect but once created the Quicktime file in all cases the image is jumping slightly, stumbling, the larger the file bigger the jumps. But once copied to a data file DVD is terrible, the picture is very jumpy and keeps on stopping.

I tried also to deinterlace although I don't think progresive should deinterlace? isn't it?

I don't know what else to try ! Why is that so difficul? Or am I doing something wrong?

I need to deliver this work and need help urgently!

Alioshka.

You are doing nothing wrong but expecting your drives to be able to play back very large files and your computer to decode the files. And don't expect the files like you are describing to play on a data DVD at all. A ProRes file should playback on a normal eSATA or FireWire hard drive (not an internal drive on a laptop) without jumping. USB2 drives might present some problems. Regardless, your files should be fine and you can check by repeating a section that jumped by going frame-by-frame. You should see that everything is there.

Oh William, that was really explaining everything - or almost,. Yes, the jumps are not really there, is just a playback problem. But even so and I'm very relieved for that still I cannot deliver a file that is jumping to a client!

So...
1.
If I deliver my QT file in an arquive that I copied in a DVD...
They should copy that file to an external hard drive firewire or eSATA in order to watch it properly?
So if they don't have it, they cannot play it i guess!
But my Imac (Proc.2.8 GHZ Intel Core 2 Duo) is not a laptop and still...

2.
It's like if DVD data was only a carrier or a security copy but never a place from where to play the video?

I think I start understanding a little more, thanks to you help man, that was great!
